Our roses are struggling this year even though the last few years they have been thriving. We live in the Midwest zone 4 and this year is the first one not in a serious drought
Looks like potentially sun scorch or a fertilizer burn. How much have you been watering it/how much has it been raining, and when/what do you fertilize with?
We haven't fertilized this year at all so it can be that. I was thinking it was sun scorch. We typically water in the morning or evening but it's by the bird bath so it can get hit with water when we fill that.
We have been water every couple of days but we have had some big rain. It might be over watered since it's in a small space
Overwatering is definitely a possibility then, but discoloration would start on the leaf tips and be more consistent throughout, and typically more yellow, which makes me think it could be something more severe. It's hard to tell because of all the leaf breakage happening, though. Try cutting back on water for a few weeks, and if it doesn't get better you might be looking at an infection like Rose Mosaic. Hopefully not though!
Bugs would explain the breakage! Though this would have to be the most extreme case of rose sawfly I've ever seen, which is why I originally discounted it.
